In Reply to: High oil pressure posted by WonderingAl on November 24, 2007 at 21:44:16:
Couple of thoughts. I have a super H that pegs the needle almost all the time. I have never worried about it. In fact, I'm grateful. However, assuming the worst: High oil pressure could be wrong oil (too thick) or, even worse, I've heard of swindlers putting gear oil or STP in a badly worn engine. Could also be that someone rebuilt the engine and used the wrong bearing sizes, meaning the clearances on the rods and/or mains are too tight. Could be you just have a bad oil pressure gauge. On the bang, if you are very lucky, a piece of carbon came loose from a dirty combustion chamber and is lodged on top of a piston, stuck to the head or partly lodged in a valve seat. You might also have a sticking valve or a broken valve spring, or a bent pushrod. I'd pull the valve cover and see if all 8 valves are moving up and down like they should. mike durhan
